Smart Shock-Activated Dust Suppression System .
Explosives go off
When an explosive event occurs, intense heat and pressure waves are released instantly, creating a high risk of rapid fire spread and serious damage.
AutoMist Detects the Waves
AutoMist quickly senses the heat and pressure waves through advanced sensors, activating the system within milliseconds to control the threat at its earliest stage.
Spiral Nozzle Water Spray turns On
Once triggered, the spiral nozzle releases a fine, high-pressure water mist that rapidly cools and suppresses the fire while minimizing water damage.
Designed for Underground Blasting Environments
When a stope or heading is fired underground, shockwaves, dust, and fumes rapidly travel through the drive — reducing visibility, delaying re-entry, and increasing exposure risk.
AutoMist is engineered to respond automatically.
Positioned approximately 40–50 metres back from the stope, AutoMist uses advanced vibration sensing technology to detect the blast shockwave. Once preset parameters are met, the system automatically activates overhead water sprays — suppressing airborne dust at the source before it spreads throughout the mine.
No manual activation.
No reliance on operator timing.
Fully autonomous response.
How AutoMist Works
1. Installation
- Mounted securely against mesh approximately 40–50m from the firing zone
- Connected to a fail-safe solenoid valve via control cable
- Integrated into existing water hose infrastructure
- Powered by 12VDC M12 battery system
2. Shockwave Detection
- Internal vibration sensor detects blast shockwave
- Intelligent logic verifies preset parameters
- Prevents accidental or false triggering
3. Automated Activation
- Timer relay activates solenoid valve
- Water sprays (installed on roof) deploy fine mist downward
- Operator-selected spray duration (0–15 minutes via internal dial)
4. Fail-Safe Protection
- If control cable is damaged or battery voltage is insufficient, the valve will not remain activated
- Designed to protect both equipment and water supply integrity
Engineered for Mining Performance
AutoMist is a modular, independent dust control system built specifically for underground mining conditions.
It integrates seamlessly with existing infrastructure and provides automated dust suppression in remote or hard-to-access environments.
Whether firing stopes or headings, AutoMist ensures fine misting control using strategically placed spray nozzles to reduce airborne particulates before they migrate through the drive.

Operational Benefits
Superior Dust Suppression
Fine misting from overhead spray nozzles reduces airborne particulates at the source — limiting dust migration through the mine.
Faster Re-Entry & Improved Productivity
By minimizing dust spread after blasting, AutoMist enables earlier ore movement and operational restart.
Enhanced Workforce Safety
Reduces exposure to hazardous dust and blast-generated fumes.
Fully Automated Response
Removes reliance on manual activation or operator intervention.
Adaptable Across Applications
Effective for both stope and heading firing operations.
Why AutoMist Matters
Blast events are unavoidable.
Uncontrolled dust spread is not.
AutoMist transforms reactive dust management into an automated, intelligent safety system — protecting personnel, improving visibility, and accelerating operational recovery.

Dust is one of those “always there” challenges in underground mining—until it isn’t controlled, and suddenly it becomes the problem. Visibility drops, re-entry slows, ventilation carries particulates further than expected, equipment gets coated, and worker exposure risk rises. The real issue isn’t just dust itself—it’s how fast it can move and how quickly it can disrupt operations.
That’s why modern dust suppression isn’t only about spraying water. It’s about deploying the right spray coverage, activating it at the right time, and automating it where possible so control is consistent—even during high-risk events like firing stopes or headings.
